Wisconsin - Specific Expertise

Key Service Specifics by State Regulation

Trinity staff bring extensive hands-on knowledge of Wisconsin environmental permitting and compliance.

From Prevention of Significant Deterioration and Nonattainment New Source Review and Title V to Registration Permits and Permit Exemptions, we navigate the Wisconsin Department of Natural Resources (WDNR) air quality permitting to streamline approvals, reduce risk, and keep projects compliant across Wisconsin’s diverse industrial landscape.

We deliver Wisconsin-specific environmental reporting, preparing and filing WDNR and USEPA-compliant air, water, and waste submittals — from emissions inventories and stormwater to TRI and hazardous waste — so your operations meet state and federal requirements and deadlines with confidence.

Wisconsin-focused EHS Auditing & Inspection Support that helps facilities navigate WDNR and federal requirements with proactive compliance reviews, onsite inspection readiness, and corrective action plans.

Comprehensive support for Spill Prevention, Control, and Countermeasure (SPCC) and Facility Response Plan (FRP) development, review, and certification. Our experienced engineers help facilities stay compliant with EPA and state requirements while implementing practical spill prevention and response strategies tailored to their operations.

Offering practical, tailored solutions that meet the needs of industrial, commercial, and institutional facilities, relying on our expertise in RCRA, TSCA, CERCLA, and industry-specific standards.

Support for your facility’s water discharges under individual and general Wisconsin Pollutant Discharge Elimination System (WPDES) permits as well as storm water permits.
